EffortlessSteven/README.md

Steven Zimmerman, CPA

Systems architect. Former CFO in PE-backed rollups and regulated turnarounds. Former Senior Editor at XDA.

A decade automating finance systems and ERPs in Python while running the departments that used them.

What I'm Working On

Verification tooling. ripr (static mutation exposure), unsafe-review (unsafe contract coverage), cargo-allow (source exception ledger), ub-review (targeted CI gate with review judgment).

Parser infrastructure. perl-lsp: Perl 5 language server that parses Perl without running Perl. 925k lines of Rust. Shipped as a built-in in Red Hat's LSP4IJ for JetBrains and Eclipse. tokmd: code intelligence for humans, machines, and LLMs.

Legacy and regulated data. COBOL copybooks, Outlook PST/OST, healthcare HL7.
